BROODER.

SPECIFICATION forming part of Letters Patent No. 769,633, dated September 6, 1904. Application filed January 9, 1904. Serial No. 188,333. (No model.)

T0 aZZ whont it In/fry concern.-

Be it known that I, J OHN PURDY, a citizen Fig. 4C is a horizontal section, and Fig. 5 is a 5 of the United States, and a resident of Newburgh, in the county of Orange and State of New York, have invented a new and useful Improvement in Brooders, of which the following is a specification.

My invention relates to an improvement in brooders; and there are several objects of the invention, among which may be mentioned the following:

First. It is my object to provide a brooder which will be doublesheathed walled, with a dead air-space between sheathings whereby to insure uniformity in the temperature throughout the interior.

Secondly. It is an object to provide a brooder in which the poultry is supplied with fresh air drawn directly from the outside atmosphere and heated to the required temperature by passing over a heated surface before entering the poultry-chamber.

A further object is to provide a brooder having a forced circulation of fresh heated air without making a draft at the floor.

Another object is to provide a brooder in which the heat of the lamp is confined within the brooder above the fioor-line.

Another object is to provide a brooder, and also lamp-box within the brooder,of maximum size and to economize in the heat generated, and in so doing provision is made for taking in the fresh air for the lamp through the floor at a point below the lamp, thus forming a circulation of heated air through the lampchamber and heater-pipes.

Still another object is to provide a safety lamp or heater for the brooder; and a still furtherobject is to provide a brooder in which the chickens can be seen under the hover without opening the covers of the brooder.

W'ith these several objects in view my invention consists in certain novel features of construction and combinations of parts, which will be hereinafter described, and pointed out I in the claims.

In the accompanying drawings, Figure 1 is a view in front elevation. Fig. 2 is a side view. Fig. 3 is a transverse vertical section.

detail.

A represents the brooder as a whole, which may be made of any suitable material and in such dimensions as may be preferred-say about four feet squarc\vith double-sheathed walls inclosing an air-space between them.

\Vhile it is my purpose for economic reasons to make the ground plans square or approximately so, I prefer to make the roof on two levels, with a vertical space extending between the ridges of the two slopes, as better shown in Fig. 2.

The interior is really divided oif into two compartments--one a hover B and the other a runway o n. communication with each other, 5

with a curtain 1 of soft material stretched between from the lower edge of the partial partition 2 from the top 3 of the hover to the floor-line. In the hover portion the heating apparatus is located. ably of sheet metal and, say, a foot square, is located at one end of the hover, it having a door 4 at one side, whereby access is gained to its interior, and an air-opening5 at a point A chamber D, prefer- 7 in its floor somewhere near its center, which extends down through the double fioor, through which fresh air from the outside is supplied to and distributed in the heaterchamber. Over this air-inlet 5 the lamp L is placed, it being supported on legs or other 30 suitable means 6 6 a short distance above the floor of the chamber, the lamp thus deflecting the inflowing air in a circular film around its base, so that all possibility of extinguishing the light is precluded. .In this way every particle of the heat of the lamp is confined inside of the brooder above the floor-line.

Any suitable lamp may be used for the purpose, although to insure against explosion or other accidentl prefer the special form shown, 9

in which there is a double chamber, the lower of which contains the oil and a surrounding chamber water, thereby preventing the oil from becoming overheated by radiation and at the same time absorbing the heat to be utilized with the other generated heat in warming the hover. A mica opening 7 is formed in the chimney, so that by opening the door 4 at any time the condition of the flame may be observed.

A double flue 8, comprising a pair of parallel horizon tally-disposed tubes, extends from the upper inner end of the heater-chamber D, approximately throughout the length of the hover at a point about two-thirds from the floor-line to the top of the hover, and through this flue the exhausted air from the heater-chamber is conducted out, its heat being utilized to assist in warming the hover, and from the opposite end of this flue a chimney 9 extends upward and finally out through the roof, and through it the products of combustion finally issue.

Fresh air is supplied from the outside atmosphere through a series of air-ducts 10, 11, 12, and 13, and three of these discharge into the hot-air box 14:, which is located immediately over the top of the heater-chamber D, it being preferably on a slight incline to facilitate and accelerate the upward and forward circulation of heated air, which discharges into the hover and distributes itself throughout the interior of the brooder, as indicated by the dotted line in Fig. 3. The fourth airduct 13 extends around the hot-air box, thereby supplying air at practically the outside temperature, which air commingles with the heated air discharging from the hot-air box. The orifices of these air-ductsare provided with slide-valves, whereby they may be entirely or partially opened or closed to regulate the supply and admixture of hot and cold air. The foul or exhaust air from the hover escapes through the L-shaped pipe 16, which is located in close proximity to the flue and chimney, whereby the heat therefrom induces an upward draft, thus insuring the escape of the vitiated air. A valve 17 is provided for controlling the size of this outlet.

Air is supplied to the runway through inlet-pipes 18 and 19, located at opposite ends of the brooder, the discharge ends of which are considerably above the floor-line, whereby to prevent drafts at the floor. These inlets are regulated by valves 20 20, similar to those previously described. The exhaust of foul air from the runway is through an opening 21 in the vertical portion of the roof, preferably in a hinged shutter 22, which may be entirely opened, if desired, and which is provided with a slide-valve 23 for controlling the size of the opening 21 when the shutter is closed.

Portions of the front, as well as the vertical part of the roof, are glazed, as shown in Fig. 1, and doors 25 25 are provided at various points in the brooder and a lid 26 at a suitable point in the roof, whereby to inspect and gain access to the interior or for the poultry to pass in or out.

From the foregoing it will be seen that I have provided a compact brooder in which the heat is uniformly distributed and economically utilized. Fresh air is supplied to the lamp, the hover, and the runway without causing drafts or uneven temperatures, while at the same time a forced circulation of fresh air is constantly created directly from the outside atmosphere.

It is evident that slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth; but,

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a brooder, of a heater having an air-inlet which is supplied with air from beneath the floor, a fiue secured to the heater and extending approximately the length of the brooder, and a chimney leading from the flue, means for admitting air to the brooder, and means for allowing the air to pass from the brooder.

2. The combination with a brooder having a heater, of fines secured to the heater and extending approximately the length of the brooder, said fiues being connected together at their outer ends, and a chimney leading from the flues.

3. The combination with a brooder provided with a heating-chamber and runway, of flues extending approximately the length of the brooder, said flues secured to the heater and connected together at their outer ends and a chimney leading from the fines, and air-ducts for supplying fresh air to the brooder.

4:. The combination with a brooder-frame, and a heater located therein above the floorline, said heater having an air-inlet which is supplied with air from beneath the floor, said heater adapted to receive a suitable lamp, of air-ducts, and a hot-air box located immediately above the top of the heater into which certain of the air-ducts discharge, one at least of the air-ducts discharging into the hover outside of the hot-air box whereby to supply fresh air from without at practically the temperature of the outside air.

5. The combination with a brooder provided with a heating-chamber and runway, of air inlet and outlet openings in the runway and brooder, said air-inlet openings supplying fresh air to the runway and brooder and the outlet-openings allowing the foul air to escape, flues secured to the heater and extending approximately the length of the brooder, said flues being connected together at their outer ends, and a chimney leading therefrom.

6. The combination with a brooder-frame, and a heater located therein, said heater having an air-inlet, said heater adapted to receive a suitable lamp, of air-ducts, and a hot-air box located immediately above the top of the heater into which certain of the air-ducts discharge, one at least of the air-ducts discharging into the hover outside of the hot-air box IIO approximately throughout the length of the brooder, the heater and flue confined entirely within the latter, and a chimney leading from the flue, with means for admitting and discharging air from the brooder.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
